is under development and subject to a disclaimer. [edit intro] Matter
is an emerging standard for communications among smart home (IoT)
devices. Matter promises to make smart home devices work with each
other regardless of which company manufactures them, that smart home
devices will continue to be usable on your home network even when no
connection to the internet is available, and that communications with
smart home devices are secure. The Matter standard is being managed by
the Connectivity Standards Alliance (CSA), the same group which also
developed the Zigbee family of smart home protocols. Matter is
proprietary, by certification. Its code and documentation are
published under the Apache License. Matter works over Wi-Fi, ethernet
and Thread. The heart of Matter is a Matter controller, a networked
software device that onboards (recognizes and configures) new Matter
devices. The controller must have Wi-Fi and/or ethernet access, and
the appropriate Matter software. If there are Thread (wireless
network) devices, there needs to be at least one Thread border router.
Helpfully, some Matter controllers are also Thread border routers, so
many homes may already have both of these. Devices which can already
act as Matter controllers include HomePost (2st- and 2nd-gen) and
Apple TV 4K:, Amazon Echo and Google Nest Hub speakers and displays,
as well as Samsung SmartThings hubs (including some refrigerators and
TV's). Every Matter network requires a smartphone or tablet app for
adding and configuring new devices. The Matter 1.0 standard consists
of the following copyrighted documents which were approved in
September of 2022 and are downloadable from the CSA website: Matter
